Abstract (en)

[origin: WO9739515A1] In a transverse flux machine, permanent magnets (12) are arranged on closed soft-magnetic rings (13) in a rotor (1). Two axially spaced apart rings (13) which are magnetically insulated from each other are provided for each phase of the transverse flux machine. The main flux, which otherwise flows in the transverse direction, flows therein exclusively in the longitudinal direction, i.e. in the circumferential direction of the machine. This embodiment of rotary, permanently excited transverse flux machines leads to a considerable simplification of their manufacture with respect to state of the art solutions. The number of phases of the machine may be selected at will. The three-branched embodiment is particularly advantageous because it allows standard converters to be used. Both inner rotors and outer rotors can be contemplated, the latter variant allowing a particularly simple winding technology. The longitudinal flux in the rotor, which does not affect the stator flux, shortens the magnetic circuit and saves soft-magnetic material. The magnetic yoke for the permanent magnets may be manufactured as a bundle of laminations, reducing eddy-current loss in the rotor caused by armature feedback and making it easier to equip the machine with magnetic boards.
